This document discusses psychological testing and its uses. It notes that tests are used to collect scientific data about individuals and can help determine growth patterns, classify students, identify those needing special assistance, diagnose academic issues, and provide information for admissions. Tests are also used for career and educational counseling. While useful, tests require proper administration to avoid issues like making broad generalizations. A variety of tests exist for assessing general intelligence, specific populations, and personality. Organizations like the Philippine Psychological Corporation provide tests and ensure their appropriate use through qualifications for test administrators.
